You have learned in class that addicion of an alcohol such as MeOH to this reaction results in a monobromide product instead of a dibromide. Draw the mechanism and all products obtained if you were to react trans-cinnamic acid with Br2 and MeOH. The reaction previously done was just having trans-cinnamic acid reacted with Br2 forming all the isomers with the double bond being broken and Br put into place.
Calculate the mass (g) of pure Na3AsO4 (s) and volume (mL) of 1.50 M HCl that are required to make 100.0 mL of a buffer solution at a pH of 6.80 and an H2AsO4-(aq) concentration of 0.100 M
Calculate the amount of heat liberated (in kJ) from 399 g of mercury when it cools from 73.0°C to 12.0°C.
When 17 mL of a solution containing .29 M Ca(OH)2 is diluted to 30 mL, a dilute solution is formed. What is the OH- concentration in 5 mL of the dilute solution?
hydrogen gas was collected over water in a eudiometer at 26 degrees c when the atmospheric pressure was 726 mm hg. What was the pressure of the hydrogen gas?
a sample of nitrogen gas is collected over water at a tempature of 23.0 c. what is the pressure of the nitrogen gas if atmospheric pressure is 785 mm hg
Calculate the total mass of acetic acid dissolved in the solution contained in the volumetric flask (f) The mass(g) of acetic acid dissolved in the solution contained in the volumetric flask came drom the 25.00 ml vinegar sample.
A gas occupies 4.71 liters at 62°C and 795 torr. What volume will it occupy if it is cooled to 17°C and compressed to 911 torr?
You have samples of approximately 8mL solution with ph ranging from 4 to 10. Calculate the volume of 1M HCIO4 needed to lower the ph to 2.5.
When diluting the juice samples with water, you did not need to be as accurate as in previous measurements. Why was the same level of precision not required?
If the measured gas pressure in a collection flask during a gas-forming reaction was determined to be 1.44 atm, and the atmospheric pressure that day was measured as 0.95 atm.
When sodium reacts with chlorine, 411 kj/mol is released. Calculate the amount of heat released if 1.37 mol of sodium form.
